application sied october 12,1903. serial No. 176,620. (No model.)

To @ZZ whom', 'it may concern,.-

Be it known that I, ELBERT O. HAsKINs, a citizen of the United States, residing at Rutherford, in the county of Bergen, State of New Jersey, have invented certain new and useful Improvements in HeatingBoilers,-of which the following is a speciiication.

. This invention relates to heating-boilers such as are used for producing steam or heating the water for steam or hot-water heating plants. i

`The Vobject of my invention isv to provide a new and improved heater of this kind, which is simple in construction, light, and economical, and presents a large lsurface to the iiame of the fire on `the grate.

In th'e accompanying drawings,in which like letters of reference indicate likeparts in all the pgures, Figure l is a vertical transverse sectional View ofv one construction of. my im- Fig.V 2 is a front view of the same." Fig. `3 is a horizontalsectional view of the'line 3 3 of Fig.' 1.

This boiler is constructed with a series of vertical hollow cast-iron sections A. In'the boiler illustrated there are four oit' these sectionsfwhich sections have sides in'contact, the sections being held together by tie-rods B,

thatpass through sleeves or necks C in the well-known manner at the top and bottom, and the several sections are unitedwith each other at the top and bottom by push-nipples D in the well-knownmanner. Thev lower portion of the front of the boiler in which the firei The boiler rests on a base J of any suitable construction, which forms the ash-pit. The

`vertical sections A are all alike with the ex-v ception, of course, loi the two side sections A',

which have solid inner and outerfwalls Z and may bev made in any suitable manner. The

vinterior sections A are cast with a vertical hollow front water-leg and a hollow rear watera vertical recess e is formed and extends from side to side of each section, which recesses when the sections are secured side by side form the lues f in front of the vertical rear i legs Z, the lower ends ofwhich lues f are by i suitable openings (shown at g in dotted lines,

Fig. 1) brought in communication with a Smoke-box t', with which the smoke-pipe c" is connected. An intermediate vertical leg Z0 is section Zby a series of upwardly-inclined jwater-legs Z, of which there are tive in each section, each having a width equal to about one-half width of the section. Two are formed 'along' one side of the section andvthree along the other side and they are staggeredHthat is to say, one is on the left side, the next one above on the right side,.the next one above o 'the' leftside and, so on alternately.l l

It will be seen that by arranging the in- .clined water-legs in this manner'the legs of theseveral sections form upwardly-inclined y rows or steps of water-legs, between which thel products of combustion can readily circulate l and which are more or less subjected directly 'to the Haines of the tire on the grate. bottom of the top water-space Z is made hori- Zo'ntahand between it and the upplmost inclined water-legs Z an approximately trian' The gular space m is formed, into which the products of combustion pass. Each vertical intermediate water-leg Za is provided with an upward extension m, connecting the upper end of `the corresponding intermediate leg Z0 with the top space cZ of the section. These extensions, however, are not the full width of.

the section, as appears from Fig. 3, but are reduced in width, so as to leave a space 0 at each side of such extensions, and the openings o of two adjacent sections establish communication between the iues and the space above the uppermost inclined water-legs Z. ln order formed in each section in front of each iiuef ,and is connected with the front leg Z of its uppermost legs Z are widened at their rear parts, so as to have the full width of the section, and are only reduced in width to conform with the other water-legs at the front portions, so as to form recesses a. The full-width portions of the uppermost water-legs thus form a baffle-plate or deflecting-plate at the bottom'of the chamber m, and the recesses a form openings at the front and top of the boiler, so as to compel the ianie and products of combustion to pass from the fire between the inclined water-legs Z to the front part of the top of the boiler, through the openings formed by the recesses n, and into the space m. By this arrangement the flame and products of combustion circulate thoroughly around all the inclined water-legs, are deiiected against the front waterlegs,.and in passing from the space m through the rear downwardly-extending iues f also serve to heat the sections.

The water-legs of the rear vertical legsb form the circulating-column of water and the intermediate legs c the distributing-column, and between them the return-flue f is formed, and thus the heat is fully utilized. p

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A heating-boiler constructed with vertical water-sections, each section having a front, intermediate and rear vertical water-leg, the front and intermediate legs of each section being connected by a series of water-legs inclined downward and toward the rear which water-legs have approximately half the width of the section and are arranged alternately at opposite sides of the section one above the other, substantially as set forth.

2. A heating-boiler constructed with vertical water-sections, each section having a front vertical waterleg, an intermediate vertical water-leg and a rear vertical water-leg, the front and intermediate legs being connected by a series of water-legs, inclined from the front downward toward the rear and arranged alternately lat opposite sides of the leg, one

above the other vertical iiues being formed between the rear and intermediate legs of the sections, substantially as set forth.

3. A heating-boiler constructed with vertical water-sections, each section having a vcrcal front water-leg, a vertical intermediate water-leg and a vertical rear water-leg, thc front and intermediate legs being connected by a series of water-legs inclined from the front downward toward the rear and arranged alternately on opposite sides of the section one above the other, the uppermost inclined leg of each section having the full width of the section with the exception of the front part of said uppermost leg so as to form a bafHe-plate and in front of same an opening for the products of combustion, substantially as set forth.

4. A heating-boiler, constructed with a series of vertical sections, each section having a front, intermediate, and rear vertical waterlegs, the front and intermediate legs of cach section being connected by a series of waterlegs inclined downward and toward the rear, and an upward extension, extending from the top of the intermediate leg of each section, to the top part of the section, which extension is of less width than the section so as to form openings for the passage of the products of combustion from above the uppermost inclined water-legs into the iiues formed bctween the rear and intermediate vertical legs, substantially as set forth.

5. A heating-boiler constructed with a series of vertical hollow water-sections having a vertical front leg, a vertical intermediate leg and a vertical rear leg, the lower ends of the intermediate vertical legs resting on a support, a water-back having a lire-door opening, upon the top of which water-back the lower ends of the vertical front water-legs rest, substantially as set forth.

In testimony whereof I have signed my name to this speciiicatiomin the presence of two subscribing witnesses, this 19th day of September, 1903.
